LTC1419ISW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1419ISW#TRPBF is a 14-bit, 800ksps sampling analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates from ±5V supplies and dissipates 150mW of power. The device features a true differential input sample-and-hold with a ±2.5V bipolar input range and a 20MHz full-power bandwidth. It includes an internal 2.5V reference and offers two digitally selectable shutdown modes: Nap and Sleep. The ADC provides a µP-compatible 14-bit parallel output with no pipeline delay. The ISW suffix indicates an industrial temperature range (-40°C to +85°C), SOIC-28 package, and tape and reel packaging.

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix confirms tape and reel packaging and lead-free compliance. Confirm the 'I' grade meets the -40°C to +85°C operating temperature requirement. Ensure the SOIC-28 footprint matches the PCB layout. Check current availability status as distribution may vary.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high dynamic range at moderate speeds. The 14-bit resolution and 800ksps rate suit spectrum analysis and imaging. Verify supply voltage compatibility with ±5V rails. Consider the internal reference stability if external precision references are not used. Evaluate power consumption against system thermal constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1419 family of 14-bit ADCs. Variants include CG (SSOP, commercial temp), CSW (SOIC, commercial temp), and AISW (SOIC, industrial temp). The ISW#TRPBF specifically denotes the industrial temperature grade, SOIC-28 package, and tape and reel shipping format.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include LTC1419CSW#TRPBF (commercial grade) or LTC1419CG#PBF (SSOP package). Cross-family replacements require verification of interface timing and power supply requirements.
